Note: If you need to write something in error.log located in the following folder <Your Apache Installation>\Apache2.2\logs you can insert the line below in your WSGI file. In our example this file is called dj_survey.wsgi. This method is very convenient to get the PYTHONPATH correct:

print>> sys.stderr, sys.path

In this file you are defining the settings that will be used by your Django application, in our example this file is called: dj_project.apache.settings_production (Note: ".py" is implicit and should not be added).
There is nothing special in that file except that I am pointing to a special urls.py which reflect the configuration I am using in production.
